Well they have not left my topic about
COVID-19.
Ah, I had no clue as to what OP was talking about, but I saw one big referral link banner in someone's post in your thread.
Honestly, I haven't seen too many members doing this else I would be reporting them. Probably I'm just not looking at the threads where they're happening, but I'll keep an eye out henceforth.
These posts are removed really fast.
That's what I'd expect if a mod is on the ball, because there's really no judgement to be made in cases like these--posting referral links and/or signature advertising outside of the signature space isn't allowed, so any post containing that annoying shit should be nuked as soon as a moderator sees the report.
